Explore button disable?

Okay here is my question
I do a complete backup choosing disk/volume
i do fixed disk

okay
Now i dont want to recover the whole machine, i just want to recover a single file

The only option i have seen its this one
Is going to the centralized vault i mean using the explorer of windows and going thourhg all the path
C:\AcronisBK\BK\computers\B2F388EE-86D1-466E-BD8D-1FB6A7546F44.0453DD75-015C-4B48-847F-4D5F061883B1\users\S-1-5-21-1006505156-1243026319-1321204895-500\archives\74DE838A-A6DD-4253-8248-6DC93DFEB381\1

Now let say i got like 10 differents computers in that vault...
how ill know which comp is which? i mean with all those numbers??? there is no way i can know that unless i go in in every one of those and check it manually...
Now that is a lot of effort and it makes no sense i do it this way...

Now what other option i got?
I though i would be able to see the computer files and doing copy past with the explore option when i go to the Acronis centralized console, vault centralized there is like a explore option which i though it would help me for that but its disable...

Anyways do you get what my issue is?
I would like to just go in the tib file and extract the single file im looking... on the backup, but if i do it in the way i have been doing it so far its a way too much effort....
i would like to do the same but knowing which machine im looking....
